About This ROM Hack
Pokémon Nidokingdom is a dark, experimental Pokémon GBA ROM hack and the developer’s first hacking project, built on Pokémon FireRed. The hack focuses on atmosphere, mystery, and environmental storytelling rather than traditional gym progression.
It presents a distorted version of Kanto where familiar towns have vanished or fallen into ruin, and Nidoran/Nidoking-related Pokémon dominate the world. The project is intentionally rough and open to feedback, with the creator actively seeking criticism on mapping, story, and scripting.
Story Overview
You begin as an ordinary kid from Pallet Town, but everything changes when you wake up one morning with no memory of who you are. Even more disturbing, your mother has been transformed into a male Nidoran.
Stepping outside, you discover that Pallet Town no longer exists. In its place lies a vast field of flowers, broken only by a small cave. Inside, you find a ransacked room and a single Poké Ball containing an abandoned Corpfish—your first and only companion.
As you travel onward, the devastation continues. Viridian City is in ruins, its destruction more recent than Pallet’s, as buildings still leave visible remains. When you finally reach Pewter City, civilization appears to persist—but something is clearly wrong.
The mystery of what happened to Kanto, why the world is ruled by Nidos, and how reality itself has shifted forms the core of the narrative.
